There was also localised flooding in Rhos on Sea on Saturday, with motorists having to drive through shallower sections of water of Glan Y Mor Road.

The huge tides, some of the biggest seen in recent years, are thought to be triggered by the gravitational effects of the Moon, which is nearing it’s closest point to Earth in it’s 18.5-year orbit.

A spokesman for Natural Resources Wales urged people to be careful in coastal areas.

He said: “We are asking people to take extra care near the coast this weekend as seasonal high tides could cause dangerous conditions.

“High tides are likely to affect most areas of the coastline.

“These areas could see localised flooding of coastal roads with the potential for spray to over-top promenades and piers.”

Spring tides were expected to peak yesterday and then begin to reduce, although the unsettled weather is set to continue into this week.

The spokesman continued: “The weather forecast for Monday remains unsettled and an increase in wind speed could cause further hazardous conditions.

“Forecasters from NRW continue to monitor tidal and weather conditions closely and will issue further warnings if necessary over the weekend.

“Operational staff are also on site at susceptible areas to watch out for any potential impacts.”

The Met Office said there will be sunshine and showers on Monday in, with hail and thunder affecting parts of North Wales.

There will also be showers possibly wintry, with snow possible on higher ground.

It will remain windy and cold with a marked wind chill.

It is expected to be unsettled for the rest of the week with milder temperatures mixed with some colder weather.

A new £1.2m coastal defence scheme to protect Beaumaris against flooding is set to begin in March.

The scheme, which will see a new sea wall built near the town’s green and other improvements along the A545 into Beaumaris, will go ahead after the Welsh Government confirmed a new funding package for the project.

Anglesey MP Albert Owen said: “I’ve seen the devastation of flooding and the anxiety of potential flooding but this scheme will assist in alleviating this and shows a clear commitment to tackling the threat of future flooding.”
